Water-marks are commonly placed on aper in the process of manufacture ona ourdrinier machine and while the paper is in the form of a continuousweb or roll.

This invention relates to a device for indicating the lines along whichthe web of paper should be cut in order to bring the watermarks touniform positions on the separate sheets into which the web is to besub-divided.

It is the object of my invention to provide a device for placing acutting mark or indication on the web during the formation thereof onthe Fourdrinier machine.

In the preferred'form of my invention, I also provide means for coloringthe markdire. tion of the arrow 2 in Fig. 1;

Fig. 3 is a sectional end view, taken along the line 33 in Fig. 2;

Fig. 4 is a sectional elevation, taken along the line 44 in Fig: 1, and

Fig. 5 is a detail View showing the mark as it appears on the paper.

Referring to the drawings, I have shown a roll to which a series ofwater-marking plates 11 are secured in the usual manner. The roll 10 ismounted above a guide roll 12 over which the web W of paper passesduring the formation thereof. The rolls 10 and 11 are caused to rotatein unison by connecting gears 14, and the roll 12 is positively rotatedthrough power COIlIlGCtlOIlS, not shown.

The bearings 15 for the water-marking roll 10 are slidable in fixedframe members 16 and are yieldingly pressed downward by levers 17 andweights 18. Downward limits of movement of the bearings15 and roll 10are determined by studs 20, threaded into blocks 21 which support thebearings 15.

The lower ends of the studs are received ing blocks 23 for the lowerroll 12. The studs 20 may be adjusted by hand wheels 24 through worms'25and worm gears 26.

The roll 10 is adjusted so that when the web passesover the guide roll12 the water-mark plates 11 will press lightly against the (lamp andpartially formed web of paper and will impress the water-mark thereon.-The relation of the plates to the web may be adjusted by the hand wheels24, and the pressure is determined by the weights 18.

The parts thus far described are of a usual commercial construction andin themselves form no part of my present invention, which will now bedescribed.

I provide an additional plate adapted to be secured by screws threadedinto selected holes 31 in the surface of the marking 1'oll10. The plate30 is provided with a marking projection 32 thereon, preferably in theform of a narrow rib extending axially of the roll 10. The outer surfaceof the rib 32 is approximately in the same cylindrical ililface as themarking surfaces of the plates As the roll 10 is rotated, the rib 32comes in contact with the partially formed web W adjacent an edgethereof and forms a mark or depression therein which may be readily seenin the finished paper. This mark is impressed once for each revolutionof the roll 10 and is always in predetermined relation to thewater-marks impressed by the plates 11. If the web of paper isthereafter out along the line of the indication 40 (Fig. 5) formed bythe rib 32, the water-marks .will all appear in a desired location inthe subdivided sheets.

The plate 30 may be adjusted on the roll 10 by selecting different holes31 and also by providing the plate 30 with circumferential slots, sothat the rib 32 may be secured in-a desired and definite relation to theplates 11.

While the cutting mark thus impressed is effective for the purposeindicated, I prefer ably provide means for inking or coloring the markso that it may be more easily detected. For this purpose I provide aninking wheel 50, rotatable in a forked support 51 mounted on a slottedsup orting bar 52 and secured in adjusted position by a nut 53. The bar52 is provided with bushings 54. slidable on studs 55 fixed in thesupporting frame 16. An adjusting screw 56 is threaded in the support 52and the end of the screw 56 is mounted in a bearing member 57 and isheld from axial movement by collars 58; A hand wheel 60 is provided forturning the screw 56, by which movement the support 52 and wheel may beadjusted radially toward or from the surface of the roll 10.

Referring to Fig. 4, it will be evident that the wheel 50 is positionedto engage the rib or projection 32 once during each revolution thereofand while the rib 1s out of contact with the web W. In this way the endof the rojection 32 receives a coating of ink or 0t er coloring matterwhich is thereafter transferred to the web W and forms a mark thereonwhich is very readily detected. As this mark is applied near the edge ofthe web, the mark will be cut off in the subdivision of the web intosheets, so that it does not appear in the finished product.

Having described the construction of my improved marking device and themethod of operation thereof, it will be evident that I have provided avery simple but effective device for marking a web in exactpredetermined relation to the water-marks thereon, so that the web maybe easily severed into sheets having the water-marks uniformly locatedwith reference to the edges of the sheets.

Having thus described my invention and marking plates secured thereto,an additional plate secured to said roll adjacent one end thereof and indefinite relation to said Watermarking plates, said additional platehaving a marking projection thereon positioned to engage the web once ineach revolution of said water-marking roll, and means to apply coloringmatter to said marking projection, thereby producing a coloredindication.

5. In a paper-making machine, a watermarking roll having a lurality ofwatermarking plates-secured thereto and an additional plate secured tosaid roll adjacent one end thereof and in definite relation to saidwater-marking plates, said additional plate havin a rib thereon ofinverted V section and exten ing axially of said roll with the top ofsaid projection positioned substantially in the same cylindrical surfaceas the surfaces of the water-marking plates and thereby engaging the webonce in each revolution of said water-marking roll and being effectiveto produce a sur ace indication only thereon.

In testimony whereof I have hereunto affixed my signature.

, the advantages thereof, I do not wish to be limited to the detailsherein disclosed, otherwise than as set forth in the claims, but what Ido claim is 1. In a paper-making machine, a watermarking roll having aplurality of watermarking plates secured thereto, a device for makingcutting marks mounted on said roll in predetermined relation to saidplates, and an inking device mounted adjacent said roll and positionedto engage said marking device at each revolution of said roll.-

2. In a paper-making machine, a watermarking roll having a plurality ofwatermarking plates secured thereto, a device for making cutting marksmounted on said roll in predetermined relation to said plates, an inkingwheel, and means'to support said inking wheel adjacent saidwater-marking roll and in the path of movement of said marking device.

3. The combination in a paper-making machine as set forth in claim 2, inwhich means is provided for adjusting said inking wheel toward and fromthe water-marking roll.
